The problem with ⌥Space is that it's hard to hit it without moving your left hand away from its base position.
As to ⌃Enter, you're right, it's not a good hotkey.
@mayuzumi
Double tap shortcuts feel significantly slower than single tap shortcuts.

The default hotkey is ⌘Space, but it's already taken by another app I use and also, I find it uncomfortable.
I want a custom hotkey.
Can you help me choose one?
What are the most common custom hotkeys that people use?

When I search for iTerm I get 3 results instead of one.
Here's what it looks like:
Does anyone know what these other results are and why they appear?
This is on a brand new MacOS installation that only has brew, zsh and a few other command line tools installed.
Thanks!
